Attorney SAFE CONSTRUCTION.

Application filed February 9, 1915.

To all whom it may concern Be it known that We, MosEs MosLER, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, and CARL BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safe-Construction, of which the following is a specification.

This invention, pertaining to safe-construction, has in main view the construction of safes of nonmachinable metal, as manganese steel castings, provided with a wallopening, in addition to the usual door-opening, the additional wall-opening being securely and permanently closed in the process of manufacturing the safe.

The invention will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1 is an elevation of the wall provided with the additional opening, a portion of the closing-plate of this opening being broken away; Fig. 2 an elevation of a portion of the margin of the additional opening; Fig. 3 an elevation of the inner edge of a portion of the margin of the additional opening; Fig. at a section of the safe-body in the plane of line a of Fig. 1; Fig. 5 a section through the margin of the additional opening in the safe-body in the plane of line a. of Fig. 1, this view illustrating the safe-body and back-plate before the holding rivets and swaging have been put into completed form; and Fig. 6 a similar view illustrating the parts in completed form.

A diversity of scale is employed in the drawings. a

In the drawings :-1, indicates the safebody, provided not only with the usual door-opening but with an additional opening through one of its walls, illustrated as the rear well, this additional opening being preferably larger than the door-opening and as large as the construction will permit; 2, a ledge integrally formed with the safe-body and projecting inwardly at the margin of the additional opening and near the outer extremity of that portion of the safe-body in which the additional opening is formed: 3, rivets integrally formed with said ledge and projecting outwardly through the additional opening: 4, the margin of the additional opening outwardly beyond the ledge:

5, a closing-plate disposed in the additional opening and resting inwardly on the ledge thereof, this closing-plate having apertures engaging over the rivets 3, this closing-plate having, preferably, its inner portion will fit within the margin of its receiving opening while its outer portion is smaller than that opening: 6, the door-opening through one wall of the safebody,'which opening may be of any usual or suitable form or character: and 7, the additional opening which has been referred to.

We have thought it well to illustrate our invention in a construction in which the additional opening is at a wall of the safe opposite the door-opening, but this is immaterial as the additional opening may be at any wall of the safe-body, even at the wall containing the door-opening, in which latter case the dooropening would be formed in the closing-plate. We have also thought it well to illustrate our invention as a square safe -body provided with a square additional opening, closed by a correspondingly square plate. but this form is immaterial.

lVhile our invention lends itself to other systems of safe-body construction our main contemplation is the employment of a safebody formed of unmachinable metal, such as manganese steel casting. The additional opening when it is in a wall other than the wall containing the door-opening, gives special facility for supporting the core employed in forming the interior of the safebody when the casting is being made. The additional large opening, in whichever wall it is disposed, facilitates the insertion of an inner safe.

The margin 4 of the opening for the dos ingplate is to be originally substantially at right angles to the plane of the closingplate, and the closing-plate is to be of such dimension that it may enter that opening and seat upon ledge 2, the outer portion of the margin of the closing-plate being smaller than the margin of the opening in which it is seated, as seen in Fig. 5 and in its edge so formed that the righthand upper corner of Fig. 4.
